I think Purina big wigs should all resign.I really don't have anything against the dog food but if I had stocks in Purina I would sell right now. Purina is advertising that if you want your dogs to live longer they should be fed 25% less. To them,one plus one doesn't equal two.What Purina should do to find out about how to feed all pets is to go to any Humane Society or SPCA shelter and ask the volunteers and and the paid workers their opinions on what they think.Maybe they will learn that one plus one IS two.
